If the cones are heated and spline ends centre punched might help. If a car is hill parked in gear, with weight on the gears, then pulled out of gear, quite a force on the retaining cones. It seems to be the only real flaw in the boxes. Under load, with all the fretting action, there must be quite a tendency to loosen the dogs.
Some time ago someone enquired about remedying worn synchro cones and it was suggested that perhaps these could be spaced. If anyone has done they would have experience of refitting cones.
And a puzzle. When in Austin and myriad similar boxes, say top is engaged what stops the female cone meandering along and contacting the bronze 3rd gear cone? Or is that what wears them? Does it explain why RNs seem to go so fast?
